The loop 10 andrigidly retains the connected re'enforcextends at an oblique angle with respect to ing rods in desired relative angular posithe longitudinal axis of the reenforcing rod tions, but which is also easily applied to 6,and bight portion 11 of this loop is thereby the reenforcing rods. positioned so as to press the rod 6 directly Another object of the present invention against underlying rod 9. The sides of the 25 lies in the provision of a tie of 'the above loop 10 terminate in offset shanks 12 and 13 character which is of simple, cheap construc which have their lower portions abutting a tion and comprises a unitary wire or red side of the rod 9. Shank 12 has a leg portion member having a loop portion adapted to 1 1 formed'on its lower portion which shank partially surround one reenforcing rod and extendssubstantially parallel along the side 30 to press said rod against another such rod of the rod9and terminates in a hook 15 which disposed crosswise of said first rod, said passes around the underside of this rod in member having oiiset leg portions extending gripping relation therewith and presses upin opposite directions from said loop porwardly upon rod 9. Shank 13 is also providtion and along one side of said second named ed with a leg portion 16 which is of greater rod, said leg portions being of unequal length'than leg portion 14 and extends in a lengths and terminating in aligned hooks, i eq i n s bs antially opposite to that of leg said hooks partially surrounding said second p g Portlon 16 also lermlnate? 1n d d urging h same toward id fi t a hook 1( which passes around the underside rod of reenforcing rod 9 in gripping relation other Objects of this invention, not at this therewlth, and which also presses upwardly time more particularly enumerated, will be upon rod A clearly understood from the following (lei p 5 i and 16 are reslhent and tailed descripfign of the same I urge oo is 10 and 17 upwardly and towards r The invention is cl arl illustrated in the tile-blight Portlon 11 100p Vv-henihe 4.; r it a d 1 tie 18 not assembled upon a'reenforcing rod, 59521 i ilg gsfm jn gfigsg 1n Viow the leg portions 14 and 16 extend substantially Of was? 0 rcefi ic n 0;; l 2 W: f in (apposite CllIGQlJlOIlS ELIlCl somewhat ppwardi 8 ly rrom the point or connection with their y f -Q #16 W t a n shanks 12 and 13 so that they form acute 50 2 1S a plilll VlGW mam respective hanks as espe;

rod 9. VThis deflection cially illustrated in Fig. 1. In the act of assembling the tie upon the reenforcing rods, the loop 10. is forced somewhat away from the hooks 15 and 17 causing a deflection. of the leg portions 14: and 16 so that when assembled on the rods they are aligned and extend substantially at right angles to their respective shanks and parallel to the reenforcing of the leg portions causes them to urge hooks 15 and 17 toward the bight portion 11 of the loop. 10 thereby firmly pressing one rod directly against the other. The plane of pressure of the bight leg portion 16 andis placed upon the rod 9, forexample,

so that hook 15 engages the underside of this rod with the loop lOpositioned over the otherrod 6. Leg portion 16 is then manipulated so sides and upper surface of rod 6, whereupon leg portion 16 is pressed downwardly and inwardly with respect to rod 9, causing hook 17 to engage the underside of this rod, therebylocking the two rods together incrosswise relation. The downward movement of leg portion 16 also causes the sides of loop 10 and shanks 12and 13. to move toward one anotherand into gripping relation with' the sides of rod 6. Preferably, consecutiveties are staggered as illustrated in Fig.72, so that the leg portions of one tie are positioned on the opposite sideof rod 9 with respect to the leg portions of the next succeeding tie.

- Owing to the obliqueness of the loop 10 with respect to rod 6, the sides of this loop obtain afirm holdupon this rod which hold extends for a distance along thelengththereof, thereby greatly adding to the rigidity with which the rod 6 is held by the loop. The greater length of the leg portion 16 over that ofleg portion 14 enables the ready insertion of the hook 17 under the reenforcing rod 9.

, The relatively great spacing of the hooks. U 15 and 17 enables the tie to obtain a firm hold on rod 9 which together with the firm hold of the oblique loop 10 upon rod 6 in addition tothe existence of adirect line of pressure between the bight portion 11, the intersecting axes of rods 6 and 9 and the hooks 15 and 17, all combine to cause the novel tie of this invention to rigidly hold the connected rods in fixed relative positions.

The greaterlength of the leg portion 16 over that of leg portion 14 enables the ready 7 and easy application of the tie to reenforcing rods. or theremoval of the tie therefrom if I desired.

i As many changes could be made in the above construction and many apparently thatthe loop 10 engages the widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. I 7 7 What is claimed is v 1. In combination a pair of intersecting concrete reenforcing rods and a'tie therefor comprising, a loop extending around a portion of one of said rods and acting to directly press said rod against the second of said rods, shanks formed on said loop and terminating adjacent a side of said second rod, oppositely extending leg portions of unequal lengths formed on said shanks and hooks provided at the ends of said leg portions and partially surrounding said second rod and urging the same toward the first of said rods. r

2. In combination a pair of intersecting concrete reenforcing rods and a tie therefor comprising, a loop extending around a portion of one of said rods and disposed obliquely to the longitudinal axis thereof and-having its bight'portion pressing said rod directly against the second of said rods, shanks formed on said loop and terminating adjacent a side of said second rod, oppositely extending leg portionsof unequal length formed on said shanks and hooks provided at the ends of said legportions and partiallysurrounding said second rod and urging the same toward said first rod and said loop, the lines of pressure of said hooks and said bight portion lying in a common plane with the longitudinal axis ofsaid second rod.

In testimony,that I claim-theinvention set forthabove I have hereunto set my hand this 8th day of November, 1929. r
